IMPROVED KURSE-SHOE MAGHINB.

. Be it'known that I, UO'HN W. KINGSBRY, of New Bedford, Bristol county, Massachusetts, have invented a new and im'provedHorse-Shoe Machine; and I do hereby declare that the following is a full, clear, an'd exact description thereof, which will enable others skilled in the art to make ond'u'se theseme, reference being had to the accompanying drawings, forming part of this specification. l

This invention relates to ani-schine for forming horse-shoes from'hot barron, the machines being so arranged as to be adjustable for all sizes of horse-shoes, and so that one shoe is formed during each revolution of the horizontal driving-shaft of the machine. v

T he invention consists in the general construction of a horizontal machine, and in themanner of imparting the required motion to the different portions, andthe invention consists also in the use of a movable and removable die, around which the shoe is formed; said die passing between -afpaiij .of rollers, whereby the straight bar which was luid previously across the said rollers, is bent into a U-shaped form. The heels`are then pressedi'n by means of a pair of jaws, which are forced against the shoe by a pair of friction-rollers, working against inclined surfaces on the frontend of the jaws, and then- 4the toehof theshoe may be flattened by being forced against an adjustable stationary block. The heels are, or mayv also be, thickened by the aforesaid jaws, which is a very important item, ns the'blanks have not to be thickened previous to their being'lput into this machine by an independent apparatus. The inner die has, duringthe aforesaid motions, been moved constantly forward, being operated by connecting-rods, 'which are secured eccentric on the driving-shaft, and are secured lto the side Aof a frame to which the said die isi-attached. The ends of these rods, which are secured to the frame of the die,ar'e slotted, and after the shoe has heen forced against the afv'offiid block or abutment, the forward movement of the die is completedr The cranklpins'onfthe drivingfsh-att, to which the aforesaid' connecting-rods are secured, are then on a level with the horizontal driving-shaft, and on that side of the shaft which isfopposite to the dies. The slotted other end of the rods has to be moved backward now until the forward end oi' thevslot strikes the pin on the frame of the die. During this Imotion the jaws are released from the shoe, and then the die is moved hack until it is brought as far back as possible.' The ready-formed shoe is then dropped through a hole in the cover of the apparatus into any suitable receptacle, While the die is at its rear position fthe connectingrods are level again, the crank-pins being on the same4 side of the driving-shaft as are the dies, and thesaid shaft must be turned to bring'the back end-'of the slot'inA contact with the lpins on the die-frame. Thisgives ample time for the in'troduction of a freshblank into the machine,so that the operations maybe resumedagain.

In the annexed drawing my-invention is illustratedv Figure-1 being a plan or top' view, partlyjn section, of my machine, showing the different parts in position for operating on the straight blank. .Y i

Figure 2 isaplan or top view of the machine, showing the parts in positionwhen the shoe has been formed, and is held between the die, jaws, 'and stationary toe-piece. v

A is an oblong frame made of wood or any other suitable material strong enough to support theother parts of this machine. B are posts or supports upon which the plate A rests. v C is the horizontal driving-shaft, which is mounted in suitable boxes, arranged on the frame A, near one end of the same. Two disks, D, are secured to the ends of the shaft., and are provided with wrist-pins a. To these pins are secured the connectingrods E, which are attached at their other ends to a horizontal sliding frame, IF, which is provided with pins b b, fitting through the slotted onds of the rods E, as shown in figs. 1 and 3; Upon the frame F- is secured, by

means of a bolt or screw, @,for otherwise, so as to be easily removed or replaced, a'rc'ciproca'ting die, G, which has the shape of the inside of the horse-shoe. This die may be replaced by one of diere'nt size, whenever di`erent-sized shoes are to be formed. l.The reciprocating die G is secured to an upright rod or pin,"ol, which is part of the'framc F, and for which n. slot, e, is'provided in the plate A, to allow it to slide forward and backward. The reciprocating die G is elevated so as to be just above the plate A, its lower surface being on the same level as the upper surface of By means of the crank-pins a and rods E, the frame F, and with it the die G, is moved alternately forward and backward. l In front of the reci procuting die G, and as far apart from veach other as the outsidcs of the shoe to be formed are fi'om cach other, are arranged two rollers, H H, andare mounted on vertical pinsff, which are secured to slottedr plates g g, the latter being secured to the platcAby means ofscrews h h, as shown. Thusrtbe rollersI-I can be moved' more or less apart, according to the size of shoe to be formcd,ns seen in figs. .3 and 4. These rollers II consist of three circular plates, one luid above the other, the centre plate being of the largest diameter, so as to l'irojcct beyond the lower plate, and to keep the metal down while it lis bcingformod. The upper and lower plates ofl the rollers AH are of different diameters, sothat'tbe said rollers may be turned around, and beV thus used for a still greater number of di'ercn'bsizcd horse-shoes. The straight blank z'is laid in rear of the rollers H and in front of thc reciprocating die .G, as shown in fig. 1. By means of spring-gauges K K the blank is held in proper position, said gnu-ges'allowing for slight variations in: the length of the blanks. When the die G is movedforwnrd, the shaft C revolving, the blank is bent out in the centre, bet\veen` thc die G and rollers H, and receives the form of the letter U, as is shown-in red lines in tig. Q It willlthen be necessary'to bend the heel-pieces in, and this is done by means yof two jaws, I I, 4which areattached to a pair of plates, Z. The plates Zn're pivoted to the table A, as shown, so as to turn readilyron their pivots, and those ends which hold the clumps are forced together intotheposition shown in fig. 2, by two friction-rollers, m, which arc attached to a block, L, 'which is connectedl by means of a rod, n, with an eccentric, o, on -the shaft C, all as shown in figs. 1 and 2. When the eccentric draws the rod it toward the shaft C, the rollers m will spread the front ends of the arms l, and will thereby force theirrear ends together. The toe of'the shoe, when to be iinttened, is forced against an adjustable stationary block, M,wh\ich may be moved forward orbachward, being slotted as shown, or against a plate, s, which is adjustable on thc stationary block M,and is enabled to receive pressure by the application of a wedge, t. Jaws I can also be adjusted on the plates [,or he removed or replaced with ease, being held in place by means of screws p. I' The heels of the shoe may be thickened by forming the jaws I accordingly, and as indicated in fig. 2. -After the shoe has been thus i formed, it wllbo necessary to move the die back to its starting place, and to remove the shoe, so as'to` be able to form a new one. But the shoe could not be moved back unless the jaws I were first spread apart, and it is important that the jaws should be opened before the dieGicomniences` tp move bacls. For this purpose I have arranged the slotted rea-r end of the connecting-rods E. While the shoe is held between the jaws I, und rocip eating die G, and block M, the rods are as show'n in fig. 2, the back end of slot being in contact with the pin la,

having been` pulling the frame F forward. 4To move the latter backward, the frontend of the slot must be brought against the pin '6. While the shaft C is being,turned,.and the frame F yand'die G are thus at a standstill, the eccentric o pushes the block L towards M, and releases` thus the pressure of the rollers m 4upon the front endsof the plates l, end tho said front ends are then moved towards' eachother by means of springs q, whereby the jaws I are spread apart, being in position shown in Iig. 1, while the dieV G u-nd the formed shocare in the position which is indicated by red lines in fig. 1. The frame F and die Gare then moved back, and when` the die arrives at itsoriginal position, (iig. 1,)'the shoe drops through an aperture, provided in the plate A, upon the floor or into any suitable receptacle. When the die ,arrives at the position shown in iig. 1, the forward end of the slot in rod E is in hcontact with the pin b, as4 shown in Vsection in iig. 1, and while the die G remains stationary during the time, the rod moves so as to 'bring the back end'of the slot in contact with the pin sudicient time is afforded to placca new blank between the gauges K. The reciprocating die -G ymay also be covered (like the lower plate of each roller H) by a plate witha projecting ange, whereby the iron'would be prevented from being bent up by the strong pressure against its sides. i All the parts in this machine may be made of steel or. of any other suitable material, and of suitable dimensions. It will be seen that iu, this machine all sizes of horse-shoes can be formed with great facility, and the heels thickened after the shoe has been formed.
